Another Photoshop Action - this lets your pictures look older. It adds some noise to it, makes it black/white with putting a white layer on it that is changed to "Color", adds 2 new layers - one filled with a bright brown tone that is changed to "Color" and another one is filled with a blue tone, the layer is changed to "Exclusion" and both layers' opacity is changed. Finally there's an adjustment layer that changes brightness and contrast of the image and it's done! Then your image looks old

When the noise is too strong for your image, you just have to set the opacity down and edit it like it fits for your image.
